CROSS REFERENCE TO RELATED APPLICATIONS

This application is a divisional of U.S. application Ser. No. 15/081,636filed Mar. 25, 2016, and is incorporated herein by reference in itsentirety to provide continuity of disclosure.

FIELD OF INVENTION

This disclosure relates to the field of drawer slides for mountingdrawers in cabinetry. More particularly this disclosure relates to adrawer slide assembly providing a push-to-open functionality and a softclose functionality while also providing a drawer face depth andalignment adjustment.

BACKGROUND

Drawer slide assemblies include slides or rails mounted on both thecabinet carcass and the drawer. The slides attached to the drawercooperate with the slides mounted to the cabinet carcass to allowtelescoping extensions while providing support for the drawer. Drawerslides typically are mounted either underneath the drawer or on thesides of a drawer. Opening devices and closing devices fitted to therails of drawer slide assemblies help prevent premature damage to therails as well as the drawer and cabinet by controlling the opening andclosing movements of the drawer. A push-to-open device provides aconsistent, controlled opening force while also preventing unwantedinadvertent opening of a closed drawer. A soft close device dampsinconsistent, user initiated closing forces and provides a controlledclosing motion.

Adjustment of the drawer face of a drawer mounted using a drawer slideassembly is important to appearance and is necessary due tomanufacturing tolerances. Drawer slide adjustment mechanisms overcomemisalignment of an installed drawer relative to the cabinet and anyadjacent drawers.

Push-to-open devices, soft close devices, as well as, drawer slideadjustment mechanisms are known in the art. However, the art fails toprovide a device attachable to a drawer slide assembly that canaccomplish all three functionalities.

U.S. Patent Application Publication No. 2005/0231083 to Garde, Jr.discloses a drawer slide assembly with a self closer apparatus thatcontrols the closing movement of a drawer and further provides avertical adjustment capability. No push-to-open functionality isdisclosed.

U.S. Pat. No. 7,802,856 to Hashemi, et al. discloses a drawer slideassembly with a push-latch device. The push-latch device includes aguide block carried by the outer slide member of the drawer slideassembly. The guide block includes a catch biased to a neutral positionby a pair of springs. The catch interacts with a pin mounted on theinner slide to retain the drawer slide in a closed position. As the pinis moved into contact with the catch, the inner slide loads a springwhich will force the inner slide towards an open position once the pinis released from the catch. No soft close or adjustment capability isdisclosed.

U.S. Pat. No. 8,801,120 to Chen, et al. discloses a self-opening andself-closing slide assembly. An open-close device includes a movableunit and a passive unit fixed to a cabinet rail, a synchronic unitattached to an intermediate rail, and a hooking unit mounted to acabinet rail. Each “unit” includes many components including frames,push members, protrusions, springs, movable members, and links which arecomplicatedly assembled and precisely positioned such that the units canengage one another. No drawer face adjustability is disclosed.

A simply assembled, compact, cost effective, and easy to operatesolution providing a soft close and push-to-open drawer slide assemblycapable of adjusting the position of the drawer face relative to thecabinet and any adjacent drawers is needed.

SUMMARY

The apparatus disclosed mounts to a drawer slide assembly, comprised ofa cabinet rail mounted to the cabinet carcass, an intermediate railslidingly engaged with the cabinet rail, and a drawer rail mounted to adrawer and slidingly engaged with the intermediate rail. The apparatusis capable of providing push-to-open, soft close, and drawer depth andalignment adjustment functionalities.

Accordingly, the apparatus comprises a housing mounted to either thedrawer rail or the cabinet rail slidingly engaged with a guide blockmounted to the other of either the drawer rail or the cabinet rail. Thehousing comprises a base mounted to either rail which includes a damper,an ejector and ejector spring, and a set of soft close springs attachedto a carriage slidingly engaged with a soft close track attached to thebase. The carriage includes a dog slidable in a direction generallyperpendicular to the direction of travel of the drawer. The dog carriesa pin having a first end slidingly engaged with the soft close track andsimultaneously engaged with a guide block mounted to another rail. Theguide block comprises a stationary part adjustably connected to amovable part via a threaded shaft and a thumbwheel. Rotation of thethumbwheel adjusts the position of the movable part relative to thestationary part and thus provides a depth adjustment of the drawerrelative to the cabinet carcass. In one embodiment, the apparatus isinstalled on a single drawer slide assembly. In an alternate embodiment,the apparatus is installed on two separate slide assemblies for the samedrawer. Rotation of the thumbwheels allows synchronization of the leftand right hand drawer slide assemblies for drawer alignment within thecabinet carcass.

The pin engaged with a set of channels, catches, and redirectingsurfaces in the guide block provides the push-to-open functionalitywhile the same pin engaged with another set of redirecting surfaces andcatches provides the soft close functionality.

In a preferred embodiment, components of push-to-open, soft close drawerslide apparatus 100 are manufactured of steel or molded plastic such aspolystyrene, PVC (polyvinyl chloride), or nylon.

Although it is disclosed that housing 104 is mounted to a movable drawerrail and that guide block 106 is mounted to a stationary cabinet rail,it will be appreciated that it is also possible, with equal success,that housing 104 is mounted to the stationary cabinet rail and thatguide block 106 is mounted to the movable drawer rail.

In use, housing 104 slidingly engages guide block 106 to provide apush-to-open functionality, a soft close functionality, and a drawerface depth and alignment adjustment functionality. The push-to-open andsoft close functionalities are accomplished with pin 315 simultaneouslyinteracting with soft close track 304 and push-to-open track 528.Redirecting surfaces along soft close track 304 and push-to-open track528 contact pin 315 forcing dog 312 to slide linearly along axis 445 ofoblong hole 440 within carriage 306.

In an “open position” where the drawer is fully retracted from thecabinet carcass via the drawer slide assembly, the state of thecomponents of push-to-open, soft close drawer slide apparatus 100 aresuch that carriage 306 is positioned proximate end 403 of base 302 andcylindrical step 313 is positioned at end 442 of oblong hole 440. End316 of pin 315 is engaged with catch 426. Piston rod 321 is fullyextended from the cylinder of damper 320. End 314 of pin 315 iscompletely disengaged from push-to-open track 528. In the “openposition,” soft close springs 323 and 324 are held in a tensioned statevia the engagement of end 316 of pin 315 with catch 426, thus creatingpotential energy in soft close springs 323 and 324 equal to soft closeforce 332. Ejector 308 is adjacent end 411 along ridge 412 and ejectorspring 322 is in an un-tensioned state.

Referring to FIGS. 6A-6D the position of pin 315 relative topush-to-open track 528 and soft close track 304 during a closingmovement and an opening movement are shown.

As shown in FIG. 6A, a user supplied force on the drawer in closingdirection 600 begins a closing movement from the “open position” to a“closed position.” As the drawer moves to the “closed position,” end 314of pin 315 first passes through opening 534 and contacts ramp 536. Theuser supplied force continues to move end 314 of pin 315 through inletchannel 530 towards redirecting surface 540. Protrusion 462 of ejector308 contacts abutment 554 of movable portion 504. Ejector force 330begins to build in ejector spring 322 as soft close track 304 continuesto move with the drawer slide while ejector 308, prohibited from movingwith the drawer slide via its contact with abutment 554, begins to slidealong ridges 412 and 414 towards cap 310 against the bias of ejectorspring 322.

As shown in FIG. 6B, end 314 contacts redirecting surface 540 whichcauses cylindrical step 313 and pin 315 to move to an approximatemidpoint between ends 442 and 444 of oblong hole 440. The movement ofpin 315 disengages end 316 from catch 426. With pin 315 free fromengagement with catch 426, soft close force 332 pulls soft close track304 and the drawer in closing direction 600 to the “closed position.”Carriage 306 slides along soft close track 304 towards cap 310 untilabutments 446 and 447 contact ends 411 and 417. End 316 of pin 315 movesthrough the length of groove 422 to adjacent recess 428. Soft closeforce 332 also biases end 314 into catch 544. The movement of carriage306 relative to soft close track 304 urges piston rod 321 into thecylinder of damper 320 which controls the rate of the closing providingthe soft close functionality. While soft close track 304 moves, thecontact of protrusion 462 with abutment 554 causes ejector 308 to slidealong ridges 412 and 414 away from carriage 306 and towards cap 310 thusloading ejector spring 322 with ejector force 330. The drawer is now inthe closed position.

In the “closed position” where the drawer is fully retracted into thecabinet carcass via the drawer slide assembly, the state of thecomponents of push-to-open, soft close drawer slide apparatus 100 aresuch that carriage 306 is positioned proximate end 423 of soft closetrack 304 and cylindrical step 313 is positioned at an approximatemidpoint between ends 442 and 444 of oblong hole 440. End 316 of pin 315is disengaged from recess 428. Piston rod 321 is fully contained withinthe cylinder of damper 320. End 314 of pin 315 is engaged with catch544. In the “closed position,” ejector spring 322 is in a tensionedstate via the contact of ejector 308 with abutment 554, thus creatingpotential energy in ejector spring 322 equal to ejector force 330. Softclose springs 323 and 324 are in an un-tensioned state.

As shown in FIG. 6C, in order to move the drawer from the “closedposition” to the “open position” an initial user supplied force inclosing direction 600 disengages end 314 from catch 544 and towardsredirecting surface 542. End 314 contacts redirecting surface 542 whichcauses cylindrical step 313 and pin 315 to move to end 444 of oblonghole 440 while simultaneously positioning end 316 in recess 428. Theinitial user supplied force in closing direction 600 also causes surface459 of ejector 308 to contact surface 472 of cap 310. Segment 470 slideswithin aperture 404 against the bias of soft close springs 323 and 324until surface 459 abuts surface 433 creating supplemental ejector force331. With end 314 released from engagement with catch 544 and theinitial user supplied force in the closing direction removed, ejectorforce 330 and supplement ejector force 331 are released which urgesejector 308 towards carriage 306 effectively forcing the drawer inopening direction 602 and providing the push-to-open functionality. Ascarriage 306 is forced towards ejector 308 by ejector force 330, end 314of pin 315 moves through outlet channel 532 towards redirecting surface548. End 314 contacts redirecting surface 548 which causes cylindricalstep 313 and pin 315 to move to an approximate midpoint between ends 442and 444 of oblong hole 440 while simultaneously moving end 316 out ofrecess 428. End 314 continues movement through outlet channel 532towards engagement with catch 550 while end 316 remains adjacent recess428.

As shown in FIG. 6D, continued application of a user supplied force inopening direction 602 moves soft close track 304 with the drawer andbecause end 314 is in contact with catch 550, carriage 306 slides alongsoft close track 304 away from cap 310. Soft close springs 323 and 324are loaded with soft close force 332 as the drawer moves in openingdirection 602. End 316 contacts redirecting surface 425 which causescylindrical step 313 and pin 315 to move to end 442 of oblong hole 440while simultaneously moving end 314 out of engagement with catch 550 andinto inlet channel 530. Soft close force 332 urges end 316 into contactwith catch 426. Continued movement of the drawer and soft close track304 in opening direction 602 moves end 314 out of inlet channel 530,past catch 550, and out of opening 534 such that the drawer can be movedto a completely open position.

Referring to FIG. 7, the position of movable portion 504 is adjustablewith respect to stationary part 502. Adjusting the position of movableportion 504, adjusts the contact point of protrusion 462 with abutment554 which adjusts the depth of the drawer relative to the cabinetcarcass. To adjust the depth of the drawer, thumbwheel 518 is rotated.Rotation of thumbwheel 518 causes threaded shaft 552 to advance orretreat through thumbwheel 552 thus adjusting the position of movableportion 504 with respect to stationary part 502. Rotation of thumbwheel518 in a first direction causes movable portion 504 to move in direction704 while rotation of thumbwheel 518 in a second direction causesmovable portion 504 to move in direction 706. Movable portion 504 canmove distance 702, generally equal to the length of threaded shaft 552.Spring tabs 539 engaged with slots on segments 506 and 508 at end 522 ofstationary part 502 limit movement of movable portion 504 in direction704. Adjusting the position of movable portion 504 on both sides of thedrawer provides synchronization of the two drawer side assembliesattached to the drawer and aligns the drawer within the cabinet carcass.The alignment of the two drawer slide assemblies ensures unencumbered,coordinated movement of the drawer slide assemblies which preventsjamming.
